JOHN G. BOSS, OFELKHART, INDIANA.

BRICK-DRIER.

To all whom it may concern:

Be it knownthat I, JOHN C. Boss, a citizen of the United States, residing at Elkhart, Indiana, have invented certain new and useful Improvements in Brick-Driers, of which the following is a specification.

The present invention relates to the drying of bricks, and has, as its object the more direct or uniform application of the air current, to the mass of bricks, and the more efficient removal of moisture absorbed by the am I The method employed and apparatus used is generally similar to that described in my prior Patent #1,072,302, granted to me September 2, 1913. That method consisted of loading and locating the cars so as to form a continuous series of cars, and continuous mass of bricks from end to end, in closing the sides and discharging the drying current from the drying air duct, through a coterminous line of piled bricks, directly into the atmosphere.

It consisted further in the new and useful construction whereby these methods were carried on. Side curtains were provided for closing in the sides of the piles of bricks,

but no provision was made for inclosing the top of the pile which was left open directly to the atmosphere.

It is now found that a more successful and efficient arrangement is one which consists in providinginstead of the side curtains previously referred to a permanent wall at either side of the car loads of bricks and between one track and the next adjoining. These walls are formed to converge near the top to form practically an inclosed' tunnel with a central'opening along its apex.

The invention further contemplates providing hinged doors suitably located on the side walls and adapted to contact with the pile of bricks on the car to completely close the side passages, or to be swung out of the way as may be desired.

With these and other objects in view the invention consists in the construction and arrangement of parts more fully set forth in the following specification, illustrated in the accompanying drawing and pointed out in the appended claims.

In the drawings: Figure 1 shows a front view of the drier, with parts shown in section, and, Fig. 1 is a similar view showing a modified form of heater. Fig. 2is a central longitudinal vertical section.

Application filed September 19, 1914. Serial No. 862,569.

In the drawing, the air ducts are shown at A, A, these being different arrangements of the ducts, as hereinafter explained. These. ducts extend the entire length of the track and' a're closed at the sides and ends and have openings upward only, so as to direct the drying current upward through the massesof brick placed above them. The air in the ducts is heated in any approved way. Heated air is'supplied to these ducts in any approved way, such as drawing heated air from cooling kilns, or drawing air through anexhaust or waste steam heater. As shown at A, thefduct is located directly beneath the trackway 3, on which run the brick carrying cars, represented at 4:. These cars are steel tru'ckslabout 7 feet long) being mounted on wheels, adaptedto run on rails in the tunnel between the ducts A or over the duct or ductj'A, if the latter are used. 7 I

The direct support for the bricks consists of a pallet formed as a frame, in which, as shown 2X4 wood scantling 5 are laid across the top, orplatform' of the truck, in number sufiicient to sustain the strips or slats 5 secured thereon. These slats are at least as wide as the thickness of a brick, and are laid about three-fourths of an inch apart. Preferably the first two courses of the brick are bottom to top throughout the entire'mass of It will "be iu'nderstood that this bricks. wooden'frame or brick supporting pallet is made wider than the car truck and extends on each sideover the edgeof the flat top of the duct, when the duct A is used, and over the flat top ofthe intermediate extension of the'ba's'e (asat 6 when the duct A is used.

The parts are so proportioned that the lateral edge of the pallet moves as close to said flat top surface as practicable, on the entrance of the car as indicated at 7. A minimum amount of space is allowed between the vertical sides of the brick piles carried on the cars, and the side and intermediate walls 9, 9', of the tunnels T, T. The pallet extends at each end, so that the end of the pallet on one car will abut against the end of the next succeeding car, and make a continuous platform, and the bricks are piled flush with the lateral end and edges of the pallets, so that, when in place the bricks of all the trucks form a continuous line or column, and are acted on as one body, throughout the entire length.

Side walls are provided as shown at 9, 9. The walls or partitions are made to converge centrally above the brick laden cars leaving a longitudinal opening 10 above each tunnel and extending throughout its length. In this form the walls of the tunnels are brought so they approach to a distance of about S-inches leaving an opening along the top of the tunnel instead of the full width of the cars, as heretofore has been the case. The object of this construction is to prevent condensation interfering with the drying in bad weather. There of course, will be a current of hot air up through this narrow channel all the time and very little possibility of the condensed moisture falling back on the brick.

At a suitable height along the central and side walls of the tunnels hinged doors 11 are provided. These doors are hinged to the walls at a distance just high enough so that the brick on the cars will clear under them. They are about eight inches wide and are adapted to be lowered after the cars have passed into the tunnels to make contact with the brick stopping the air current which ordinarily would escape through the small opening between the permanent walls and the brick loaded on the cars. Cords 12 passing over pulleys are provided to raise and lower these hinged doors, and it will be understood that they are raised in order to allow the cars to enter the tunnels and then are released and dropped down onto the upper surface of the brick. In the drawing they are shown in both their raised and lowered positions.

The ducts when provided with interior heating appliances, are openat both ends for the admission of air, in proper amount. When the ducts are located directly beneath the tracks, openings at proper intervals are made in the top of the arch, as shown at 8, of four inches in diameter. But when the ducts A are used, similar air passages 8 Gopies of this patent may be obtained for are made in the side walls of the duct. In both cases the dry air from the duct is discharged into the closed space beneath the piled bricks and is free to rise up through the mass.

What I claim is 1. An apparatus for drying brick comprising a track channel, brick carrying cars to run on said track within said channel, converging walls built above said track channel forming an open topped tunnel in which said brick laden cars move, and a duct for supplying a drying current of air up through said track channel and into the tunnel, substantially as described.

2. An apparatus for drying brick comprising a track channel, brick carrying cars adapted to run on said track within said channel, side walls forming a tunnel above said track channel and sufficiently spaced apart to allow the passage of the brick laden cars, said walls converging at the top to leave a narrow longitudinal opening above the brick on the cars, av duct for supplying a drying current of air to said track channel, and means on said converging walls for controlling the upward passage of drying air at the sides of the car loads of brick, substantially as described.

3. An apparatus for drying brick co1nprising a track channel, brick carrying cars adapted to run on said track within said channel, side walls forming a tunnel above said track channel and sufliciently spaced apart to allow the passage of the brick la den cars, said walls converging at the top to leave a narrow longitudinal opening above the brick on the cars, a duct for supplying a drying current of air to said track channel, and hinged doors attached to said tunnel walls adapted to contact with the bricks piled on said cars to prevent the escape of air at the side passages between the walls and the bricks, when desired, substantially as described.

In testimony whereof, I Hill my signature in presence of two witnesses.

JOHN C. BOSS.
